Shelf

Disk Shelf Maintenance Procedures

This section provides procedural details for customer replaceable units (CRUs) of any
disk shelf in the Sun ZFS Storage 7000 family of products.
Refer to Disk Shelf Overview for component specifications and diagrams.

Prerequisites

Read the information in the overview section for your controller and become familiar with the replaceable parts of the system:

Electrostatic Discharge Precautions

Before handling any CRU, discharge any static electricity by touching a grounded surface.

Do not remove a CRU from its antistatic protective bag until you are ready to install it.

After removing a CRU from the chassis, immediately place it in an antistatic bag or antistatic packaging.

Handle any card that is part of a CRU by its edges only and avoid touching the components or circuitry.

Do not slide a CRU over any surface.

Limit body movement (which builds up static electricity) during the removal and replacement of a CRU.

Tasks

Shelf Tasks

Replacing a Drive

The shelf drives are hot-swappable and may be replaced without removing power
from the shelf. The replacement drive must be of the same capacity
and type as the drive to be replaced. To avoid possible data
loss when removing non-faulted drives, label each drive with the number of
the slot from which it was removed and reinstall each drive into
the same slot.

Faulted drives are indicated by an amber LED. Go to the Maintenance
> Hardware section of the BUI and double click the shelf thumbnail
to view Details for HDDs or to turn on the locator
LED.

Locate the failed disk drive at the front of the chassis.

Press the release button in and to the right to release the
ejection lever.

Pull the ejection lever fully open to unlock and partially eject the
drive from the chassis.

Grasp the middle of the drive body and pull it toward you
to remove it from the chassis.

Ensure the new drive ejection lever is in the fully extended position.

Align the new drive with the open slot and slide the drive
into the disk chassis.

Push the drive into the chassis slot until the ejection lever engages
the chassis connectors and begins to swing closed.

Press the ejection lever closed until it locks in place to seat
the drive and lock it into the chassis. The Activity LED with
be steady green to indicate a ready state.

Go to the Maintenance > Hardware screen of the BUI. Click
for the controller and then click HDD to verify that the
icon is green for the newly installed disk.

Replacing a Power Supply

The power supplies are hot-swappable and can be replaced without removing power
from the system. The power supplies can produce high energy hazard and
should only be replaced by instructed individuals with authorized access to the
equipment. Failed power supplies are indicated by an amber LED on the
rear panel, see the Shelf Rear Panel illustration. Go to the Maintenance > Hardware
screen of the BUI. Double click the shelf and then click PSU
to view details or to turn on the locator LED.

Locate the chassis and failed power supply.

Ensure the power supply on/off switch is in the "O" off position.

Disconnect the power cord tie strap from the power cord and unplug
the power cord from the power supply.

Using your thumb and forefinger, unscrew both ejection are captive screws until
loose and swing the ejection arms out until they are fully open.

Pull the power supply out of the chassis, being careful not to
damage the circuit board connector extending from the back of the power
supply.

With the ejection arms fully open, slide the new power supply into
the chassis slot until it contacts the chassis backplane and the ejection
arms begin to swing closed.

Push the ejection arms closed fully and secure both captive screws to
seat and secure the power supply in the chassis.

Ensure the power supply on/off switch is in the "O" off position.

Plug the power cord into the new power supply and attach the
power cord tie strap to the power cord.

Place the power supply on/off switch to the "I" on position. The
Power status LED should be a steady green and the Power status
LED and Fan LED should be off.

Go to the Maintenance > Hardware screen of the BUI. Click
for the controller and then click PSU to verify that the
icon is green for the newly installed power supply.

Replacing a SIM Board

The SIM boards are hot-swappable so you can replace them without removing
power to the system. The SIM boards are multi-pathed, so you can
remove one of the SIM boards at any time, regardless of the
state of the blue SIM OK indicator. A faulted SIM board is
indicated by an amber LED.

Locate the failed SIM at the back of the disk tray.

Label and disconnect the tray interface cables.

Use two hands to disconnect the SAS cable. Grasp the metal body
of the connector with one hand and firmly grasp and pull the
tab gently toward the connector body with the other, then pull the
connector body outward to extract it from the bulkhead. Do not twist
or pull the tab in any direction other than parallel with the
connector body or it may break. If the tab breaks, use a
small sharp object (such as a fine-tipped screwdriver) to lift the metal
spring at the top of the connector shell to unlatch it.

Loosen the two extraction arm captive screws using your thumb and forefinger.
If the captive screws are too tight to loosen by hand, use
a No.2 Phillips screwdriver to loosen each screw.

Pull each ejector tab outward and push to the sides to release
and partially eject the SIM from the chassis.

Grasp the middle of the SIM board and slide it out of
the slot.

With the ejector arms in the full open position, align the new
SIM board with the open slot and slide it into the tray
until the ejector arms contact the tray connectors and begin to swing
closed.

Swing both ejector arms in until they are flush with the SIM
board panel to seat the board.

Tighten both captive screws to secure the board.

Reconnect the SAS interface cables to their original locations.

Wait approximately 60 seconds for the SIM board to complete its boot
process, at which time the Power LED should be solid green and
the SIM locate LED should be off.
